What do you actually mean by the 'menu bar'? Do you mean the dock? The only way to get it to show all items is to reduce the size of the dock.

I mean the menu bar at the top of the screen, what's called a panel on ubuntu.

Is there even enough space to force it to show all menu bar items? Have you tried hiding your name to increase the space available for icons? There are plenty of guides on how to do so.

Yes, there is space.Between "Help" and the stack exchange notifier there should be the dropbox icon.

You say there is space, but from your image i wouldn't consider that space, even if there is technically enough of it to accommodate the Dropbox icon! Try hiding your name as i suggested?

This way I get a different resolution, I would stick to the one I'm using, which is optimal.Maybe changing just the menu bar icons resolution and keep the current resolution for the rest of the screen? Is that doable?

I have no idea on a mac. On the flip side, on windows some of those icons can auto hide themselves in a sort of hiding menu. Maybe apple does something similar that would allow you to only show the ones you really absolutely needed out 100% of the time. Like, clock, temp, volume? Changing the text size could work too if that's possible maybe, or the spacing between the menu items possibly. I have no idea if that stuffs possible though.
